Abstract: The present disclosure is related to a 5th generation (5G) or pre-5G communication system to provide higher data rates than a 4th generation (4G) communication system such as long term evolution (LTE).A method for adjusting a receive beam gain by a user equipment (UE) in a wireless communication system is provided. The method includes estimating a received signal quality value based on a reference signal received from a base station (BS), transmitting information about the estimated received signal quality value to the BS, comparing the received signal quality value with a minimum received signal quality value required for successful reception of data from the BS, and adjusting a receive beam gain to be used for data reception by turning on/off a radio frequency (RF) chain formed for each of antennas included in the UE based on a result of the comparison.

Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate successive to a 4G communication system such as LTE. The present disclosure provides a communication method of a Base Station (BS) using an Integer Forcing (IF) scheme in a Multi-User Multiple-Input and Multiple-Output (MU-MIMO) communication system, the method including: receiving a reception signal including a desired signal transmitted from at least one User Equipment (UE) served by the BS and an interference signal transmitted from at least one UE served by a neighboring BS; determining an IF filter considering the interference signal based on information on the interference signal received from the neighboring BS; filtering the reception signal using the determined IF filter; and detecting or decoding at least one of the desired signal and the interference signal using the filtered reception signal.
